MAGNETIC TACK-HAMM ER.

SPECIFICATION forming part of Letters Patent No. 710,615, dated October7, 1902.

Application filed lune 13, 1902.

To (all 11171/0711, t may cm1/cern:

Be it known that LARTHUR R. RoEEn'rsoN, of Somerville, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Magnetic Tack-Hammers, of which the following isa specification.

This invention relates to devices for facilitating the driving of tacksvor small nails at elevated or otherwise distant points which cannot bereadily reached by the hand of the user. The object of the invention isto provide a device of this character which may be utilized to readilydrive a tack horizontally into an elevated vertical or somewhat-inclinedsurface or directly upward into a ceiling or other horizontal overheadsurface. The device, however, is not limited tothe driving of tacks ornails in elevated or other locations difhcult of direct access.

The invention consists in the article and the construction thereof,substantially as hereinafter described and claimed.

Of the accompanying drawings, Figure 1 represents in a perspective Viewone embodiment of the invention. Fig. 2 represents a section lengthwiseof the hammer-head and through a portion of the handle. Fig. 3represents in perspective a method of using the device without thehammer-head, said figure also showing an extended handle.

The same reference characters indicate the same parts in all thefigures.

The hammer-head represented at d may be generally of the type shown inPatent No. 352,070 of November 2, 1886, said hammerhead having itspointed end bifurcated and magnetized to form a horseshoe-magnet. Thismagnetic hammer-head is removably connected with the handle by means ofa second magnet b,which at its outer end is formed substantially thesame as the pointed portion. of the hammer-head d. This second magnet bis suitably secured, as by means of a pointed extension c, in the end ofa handle d. The space ein the magnet b has several f unctions: First, itresults in the said magnet being of an elongated horseshoe type; second,it enables the two legs of the magnet to yield for the purpose ofapplying or removing the hammer-head d, as hereinafter described, and,

(No model.)

third, it provides a space for the pins, which will be presentlydescribed.

The outer end of the handle is preferably inclosed within a ferrulef,which may be of any ordinary type.

, The outer ends of the two legs ofthe magnet b are slightly flangedoutward, as at g, which flanges when the hammer-head d is in place, asshown in Figs. l and 2, project outward or apart from each other overthe outer surface of the hammer-head, so as to hold said hammer-headdown against the end of the handle d. By pressing the two legs of themagnet b toward each other, as by pinching the flanges g, thehammer-head d may be readily removed from the handle, leaving the devicefree to be employed for the purpose of driving a tack by means of adirect endwise thrust of the handle. This use for the device isillustrated in Fig. lVhen the device is in this condition, it may beused to drive a tack 15 directly upward into a ceiling or at a distancebetween two objects which would render the tack-receiving surfaceinaccessible to the hand of the user or in such a place that wouldprevent the hammer-head Ct being inserted and operated.

To prevent the hammer-head d from becoming accidentally removed from thesecond or holding magnet b, any suitable wedge or plug may be drivenbetween the legs of said second magnet l). I have represented at 7L apin or screw which passes through the side of the hammer-head a near itscenter and into the space between the legs of the second magnet. Thispin 7i serves to hold the legs of the magnet l) spread, so that theanges g will prevent accidental displacement of the hammer-head d; butwhen said pin h is removed the legs of the magnet b may be forcedtogether, as above described, to enable the hammer-head a to be slippedod.

As an additional means for holding the second magnet hin the handle apinimay beset permanently through the handle and through the bottom ofthe space e, as represented in Fig. 2.

It will be readily understood that when the hammer-head d is in theposition as shown in Figs. l and 2 the magnetic attraction of the secondmagnet l) will be exerted to a sufdcient ICO extent through either Wallof the hammerhead d, so that the latter may serve to pick up a tack or,to enable a tack to be so placed against it that it may be driven by asidewise or ilatwise blow of the hammer. A

The enlarged portion d of the handle shown in Fig. l may be removed andreplaced by one or a number of jointed sections d2, as represented inFig. 3, the jointed connections of the several parts of the handle beingof an ordinary type, such as the screw-threaded one shown at the bottomof Fig. 2. y

1 claiml. A device of the character specified, comprising a handlehaving a magnet fixed to its outer end, and a magnetic hammer-headremovably connected with said fixed magnet.

2. A device ofthe character specified, comprising a handle having amagnet secured thereto, the end of said magnet protruding from and in aline with the axis ofsaid handle.

A device ot' the character specilied, comprising ahandle, and a magnetcarried thereby and projecting therefrom, the projecting portion of themagnet being split, and the other end of the magnet being tapered andembedded in said handle.

4. A magnetic tack-hammer comprising a handle, a bifurcated magnetprojecting therefrom in the direction of the length of the handle, and amagnetic hammer-head mounted on and removably connected with theprojecting end of the first-mentioned magnet.

5. The combination with the handle d,ofthe bifurcated magneti) securedtherein and having its projecting ends formed With anges,

nd the magnetic hammer-head a having an opening extending therethrough,the ends of the magnet b which project from the handle extending throughthe opening of the hammer-head d, substantially as and for the purposedescribed. v j

In testimony whereof I have affixed my signature in presence of twoWitnesses.
